[PATCHv2 00/14] arm64: eBPF JIT compiler

[Zi Shen Lim]

Hi Will, Catalin,

This is a respin of series implementing eBPF JIT compiler for arm64,
on top of 3.17-rc2. The v1 series [1] missed the previous merge window.

Patches [1-13/14] implement code generation functions. Unchanged from v1.

Patch [14/14] implements the actual eBPF JIT compiler. Updated from v1:
straightforward fixups due to changes from net.
Please see [14/14] for detailed change log.

This series is applies cleanly against 3.17-rc2 and is tested working
with lib/test_bpf on ARMv8 Foundation Model.

Will had previously reported that v1 series works on Juno platform.
Since v2 only involves straightforward renaming in [14/14], I don't
anticipate any regressions.

Thanks,
z
